JONT FOR SLIDING-SIDE CRIBS.

Lirama. j

T0 all idiom it may concern .Be it known'that I, WILLIAM B. FOSTER,

'of Utica, `in the county of Oneida and State make and use the same, reference being had to the accwm'panying drawings, and to the reference-numerals marked thereon, which ,form part of this specification.

My present invention relates to joints for sliding side cribs such as are used to slide ingly mount the sliding side of a crib upon the vertical guide rods of the crib.

The purpose of my invention is to provide an improved device of the character described and one that is econoi .ical in construction and more efficient and convenient than the joint heretofore commonly used.

lt is a further purpose of my invention to provide a vdevice of the character described wherein a washer of felt, fiber, wood or other noninetallicV material is interposed between the material of the guide rod land the 'metal of the end of the sliding side mounted on said` guide rod and'moreover to have this washer allowed movement lon-- gitudinally of the sliding side rod so that the said washer may adjust itself to variations in distance between the two guide' rods upon one side of the crib. By providing for such movement the-washer may be fitted milch more tightly against the guide rods and will maintain such relatively tight fit because the operation of the sliding side will not tend to wear or elongate the hole in the washer. v i

A still further purpose of my invention is to inclose said washer of felt, or other somewhat elastic material withinla casing, which casing is at all times between the washer and the metal of the elongated slot of the sliding side ends. The inclosing of the washer in this casing enables the washer to be held more firmly against the guide rod and permits the washer to more easily slide in the longitudinal slot of the sliding side ends than would be. the case if the felt made direct contact with the metal of the slot.

A further advantage of this feature of my invention is that it allows the washer of felt or similar material to be held under con- Specification ofLetters Patent.

siderable compression and thus irmlyagainst the guide rod while `the casing prevents the washer expanding against the slot which wouldprevent the sliding motion of a washer of expansive material.

lFurther objects of my invention will be apparent from the detailed specification and from the claims hereinafter set forth.

Figure 1 is a side elevation of a sliding side crib illustrating my invention. Fig.v 2

is a side elevation of a part of a` guide rod and the adjacent end of the sliding side rembodying my invention; Fig. 3 is a vertical 'sectional view .of the parts shown in Fig. Fig. d is a horizontal sectional `view on line 4 1 `of Fig. 2 and Fig. 5 is a horizontal sectional view on line5-5 of Fig. 3. Fig. 6 is a vertical sectionai view on line 6 6 of Fig. 5. Fig. 7 is a top or bottom view of the washer inclosed in its Casing. 8 is a top or bottom view of the pro jecting end of the sliding side as seen in Fig. al. but without the washer, the casing or the guide rod. Fig. 9 is a horizontal. sectional view similar to Fig. 5 of a modified form of my invention. j

Referring to the drawings in a more particular description, Fig. l shows in side ele vation the common form of a sliding side crib wherein the sliding side consisting 0f top and bottom bars 11 connected by uprightrods 12 is slidingly mounted at eachend upon vertical guide rods 13 at each end of the crib as by having the projecting ends of the bars 11 provided with a vertical slot 14 extending longitudinally of the said bar and receiving therein the said guide rods 13. The guide rods 13 are mounted in vertical position as by means o'f their ends 15 'being bent to the posts at the top and bottom, and suitably secured thereto. The corner' posts on each side are securely connected to each other in any desired way by the usual con-v necting rails 17 affording support for the springs 1S in the usual manner.

The ends 19 of the top andbottombars 11 of the sliding side are provided with verticall slots 14e extending `longitudinally of said side and the said slot 1-1 between the top and bottom of the said end 19 is cut away or so shaped as to provide a recess 2U extending into the material of said end 19 from the main opening of said slot so that said end forms a housing in which is se* cure] y located a 'casing 21 adapted 'to slide in said housing longitudinally of said slot.

pansive and readily sliding upon the vertical guide rod 13 without noise.

The washer 22 is preferably au annular ring of desired material as felt, leather, wood, liber'or other non-metallic substance having a central aperture of such size as to snugly slide upon the vertical rod 13. The casing 21 will also preferably be in the form of ari anni lar 'ring encircling the washer 2Q and having at top and bottom an inwardly extending flange 23 turned back over't'he top and bottom respectivelyv of the said washer to a point approaching.. the aperture ltherein. This casing will holdftlhe washer from expansion diametricallyfor transversely against the surroundin surfaces of the housing and will also `hol the felt in desired state of compression against the guide rod 13. It will be obvious that the washer thus incased will slide longitudinally therewith and will thus permit of much `freer motion of said washer'longitudinally of the slot than would be the case were the washer permitted to engage the housing directly.

It will now be seen that by providing a Washer which has a motion longitudinally of the ends the sliding side and particu larlyI where easy motion ot said washer is insured by keeping it from expanding against its housing, the sliding side can be readily operated notwithstanding the lact that the guide rods at opposite ends of' the side may not be parallel. llt will be further noticed that if desired the washer may be made slidable only on one end of each top or bottom bar 1l of the side and the washer at the other end may be of the usual nonsliding character.

lt will be noted that this provision Vfor longitudinal movement of the washers rela- 'tive to the sides allows the washers to it the guide rods more closely than would otherwise be thee-ase and thus avoids -an unpleasant looseness or rattling of the side and also prevents the wearing or elongating of the aperture in a washer vwhich results where the washer `has to adjust itsel'll to unequal distances between the guide rods withoutV the washer itself being permitted corresponding mover .ent.

lt will be'understo ^l that vvarious modifr cations from the forni of the device illustrated and described may be made' without departing from the spirit of my invention.'

F ig.'9 is a horizontal sectional view illustrating a modified form of my invention. In this form a washer Q2 A is used in the elongated recess 20 without a. casing 2l being interposed between the washer and the walls of said vrecess 20. This allows the de- :ultima sired longitudinal adjustment of the washer in recess 20, and is adapted to secure a sufficient 'freedom of motion when the washer is composed of relatively firm material such as wood, fiber or wellV compressed felt.
